Question

Lisa brought half of her savings to the bakery and bought 12 croissants for $14.20. The amount of money she brings home with her is more than $2.00. Use an inequality to find how much money she had in her savings before going to the bakery. (Write the inequality that represents the situation, and solve it.)

Answer 1

Before going to the bakery, Lisa had more than $32.40.

Explanation:

Hi there!

Let x be Lisa´s savings.

She brings half of her savings to the bakery and expends $14.20. What is left is more than $2.00. Then:

x/2 - 14.2 > 2

Let´s solve the inequality:

x/2 - 14.2 > 2

Add 14.2 to both sides of the inequality.

x/2 > 2 + 14.2

x/2 > 16.2

Multiply by 2 both sides of the inequality.

x > 32.4

Before going to the bakery, Lisa had more than $32.40.
